You don't explain what this is in the description. You show the Wondertainment advertisement, and then you dive straight into the SCPs behavior. P

The collapsibles are unnecessary, as well as that last addendum.

You have a ton of details and small effects in this SCP that makes it a mess. It repairs its own cuts and refills its helium, it turns other people into balloons, and they're memetic (not memetic, they're a visual cognitohazard) that makes kids want to swallow helium, and they can be folded into things that work like real life objects (I think?).

I'm not saying that you can't have all of these effects, but the way you describe them is confusing, and I would rather have several small paragraphs explaining what the balloons can do, rather than a few sentences/blocks of texts.
